Crazy in Love (Rosewood River #4) by Laura Pavolv

"Emilia Taylor hates me, which is absolutely fine by me, because I don't particularly care much for her either. Maybe I took things too far, but I decided she was the enemy a long time ago, and she gave me no reason to think differently. At least not until recently. And when she sets her mind to prove me wrong, she goes all in. I'm willing to admit when I'm wrong--because it sure as hell doesn't happen very often. But being vulnerable with a woman I was convinced was out for my family is a big pill to swallow. So, I'd rather send her a fancy gift and call this vendetta done. However, she is anything but predictable. She doesn't want a fancy gift from a man who she's declared a broody heartless billionaire"
